The Naval Commandos was one of the last movies Chang Cheh made in Taiwan before returning to the Shaw studio in Hong Kong. It was produced in cooperation with Taiwan’s Central Film Company, and like 7-Man Army, the Taiwanese military assisted with the filming by providing vehicles and other tools of war to make the film realistic. This is evident throughout the film, but it is the most prominent during the film’s introduction and frame story. It depicts a training exercise simulating the many pieces involved in a successful beachfront invasion (similar to the D-Day invasion shown in Saving Private Ryan or The Big Red One). It works beautifully to set the stage for the wartime action drama to follow, as well as serving as a large-scale display of power for the Taiwanese military.

This introduction is great, and it perfectly frames the film, but the film’s primary story is far more interesting. Many years prior during the Second Sino-Japanese War, when the Chinese Navy was less advanced, the Japanese cruiser Izumo (referenced as Izuma in the subtitles) was docked in Japanese-controlled Shanghai in preparation for further attack on China. The Chinese Navy had nothing that could stand up to the Izumo in direct battle, so it is decided that a small group of men aboard a torpedo boat will try to perform a sneak attack disguised as a fishing boat. Getting there is not so easy, though, as there is a huge field of mines to be crossed and Japanese patrols to elude. It is a valiant plan in theory, but unfortunately it is derailed before it even has a chance of success. The men arrive in Shanghai, undeterred and focused on finding a new method of sinking the Izumo.
